The Features of Resin Manhole Cover
The Resin Manhole Cover is made of polymer composite material, with deformed steel bar as the main skeleton. After high temperature molding, the strength can withstand 50 tons of weight.
The manhole cover have light weight, convenient for transportation and installation, and can greatly reduce labor intensity. The new resin manhole cover has excellent anti-theft performance, because the resin material has no recycling value, effectively eliminating the appearance of “urban black hole”.
The Composite Manhole Cover has high precision and corrosion resistance. It is produced by high temperature molding and has good acid and alkali resistance and corrosion resistance, which effectively prolongs the service life of the resin manhole cover.
With the continuous development of technology, the manhole cover has been rapidly developed as a common material for municipal and construction. Let me talk about the installation precautions for the composite manhole cover:
1. The masonry of the manhole cover shall be determined according to the size of the manhole cover designed by the design institute or the length by width and square circle and implemented according to the reference standard. Concrete protection ring with a width of 40 cm shall be cast on the periphery of the manhole cover for maintenance. The period will be more than 10 days.
2. It is necessary to pay attention to avoid the construction machinery directly crushing the well seat. When the whole road surface is cast, the hole larger than the well seat should be reserved on the road surface and placed after the asphalt is laid.
3. After the concrete is cast or asphalt paved, the manhole cover should be opened and cleaned in time to prevent the mortar or asphalt from inspecting the manhole cover and the seat into one, so as not to affect the opening in the future.
